Local authentication can be tried first, followed by remote, if the local authentication fails
(Local/Remote_Method).
-or-
Remote authentication may be tried first, followed by local (Remote_Method/Local).
-or-
Local authentication may be tried only if a remote authentication server is down (Remote_Method_
Down_Local).
An administrator can configure authentication using the CLI utility and the web manager. The
default authentication method for the console server and the serial ports is Local. Any
authentication method that is configured for the console server or the ports is used for
authentication of any user who attempts to log in through Telnet, SSH or the web manager.
Appliance authentication
The console server authenticates for the console server and the ports, either in groups or
individually.
NOTE: It is advised when using group authorization that you use the same authentication for both the
console server and all serial ports, or use Single Sign-on Authentication to facilitate group authorization.
When Single Sign-on Authentication is disabled, the console server uses the individual
configuration based in the destination of the access: the console server itself or each serial port.
Users must use their password each time they access an individual port. If enabled, Single Sign-on
Authentication will use the authentication server you choose from the pull-down menu for all access
and no further authentication will be needed.
NOTE: Selecting unconfigured from the pull-down menu will allow the ports to continue to use individual
authentication servers, and will require your password the first time you access any port. After that, the port
will not require password authentication if Single Sign-on Authentication is enabled.
To set authentication for the console server:
1. Click Authentication - Appliance Authentication.
2. Select the desired authentication server from the Authentication Type drop-down menu.
3. Select Enable fallback to Local type for root user in appliance console port when the remote
authentication fails and an administrator wants to access the appliance via console port as the
root user.
